Title: Single-tube colour television camera
IPC: H04N9/07
Filed: 1970-09-17
Abstract: 1,273,338. Colour television camera. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 17 Sept., 1970 [20 Sept., 1969], No. 44502/70. Heading H4F. A colour television camera with a fieldsequential pick-up tube is provided with a converting system for generating simultaneous colour signals by utilizing the storage properties of the tube target, the scanning beam being interrupted in each line (of the order of 100 times) in a regular manner which varies from field to field so that the output signal for a given line in (say) the red field period is modulated in a regular manner by addition of green and blue intensities. By provision of tube output switching synchronized with the interruption rate and arithmetic combination of the switched outputs the colour signals may be reconstituted by the use of two delay lines having delays small in comparison with the interruption period. Fig. 2 illustrates scans V1-9 over a single line in red, green and blue fields successively in which unit target areas (only 24 of which are shown) accumulate electric charge until read out by the beam (interrupted by a unity mark/space ratio square wave as indicated by the breaks in the horizontal lines). After an initial start-up period of two fields the output patterns of V3, V4, V5 are repeated cyclically, and by the use of a commutator arrangement the elemental scan outputs are routed during successive fields to lines P, Q, R as shown in the lowest three lines of the Figure, of which Q always represents r+g+b (or luminance). By use of analogue subtractors, and delays of one and two elemental scan times the red green and blue signals are derived from the P, Q and R signals and after matrixing these may be combined with the luminance signal and delta corrected, the schematic layout of such a system being illustrated in Fig. 1 (not shown). The principle is also described as applied to a two-colour pick-up tube, in which the line scan is interrupted at each third elemental area. A method of eliminating the effects of incomplete charge neutralization by applying compensatory signals to the subtractors is described.

Abstract: 1,123,170. Stacking devices; endless conveyers. H. LINGL. 12 Oct., 1966 [15 Jan., 1966], No. 45600/66. Headings B8A and B8C. Brick blanks 11, supplied in longitudinal rows from battens 10 by a grab 12, are carried by a feed conveyer 1 as far as a fence 3 at the end of the conveyer to align the rows transversely. The fence is raised and the first transverse row of bricks is transferred to a conveyer 4 running at the same speed as conveyer 1. The drive to conveyer 1 is stopped until the first row has moved a required distance along the conveyer 4 when the drive to conveyer 1 is restored to transfer the second transverse row. In this way the distance between rows of bricks on the conveyer 4 may be regulated. The control of the conveyer 1 may be effected by programmed discs (7), Fig. 5 (not shown), selected by means of a switch (9). Each layer of bricks is lifted by a grab from the conveyer 4 and placed on a kiln truck, forming a square stack. In a modification designed to produce a rectangular stack on the truck, a separate conveyer runs on each side of the conveyer 1. A first layer of bricks is transferred to conveyer 4, using the conveyer 1 in conjunction with the side conveyers, but a second layer is transferred using only conveyer 1, a layer being formed equal in length to the width of the previous layer. When placed on the truck the second layer is rotated through 90 degrees relative to the first. The bricks may be supplied to the conveyer 1 by a pushing device.

Title: Electromagnetic striker mechanism for a printer
IPC: B41J9/38
Filed: 1974-10-22
Abstract: 1482009 Electromagnets COMPAGNIE INTERNATIONALE POUR L'lNFORMATIQUE CII-HONEYWELL BULL 22 Oct 1974 [6 Nov 1973] 45713/74 Heading H1P [Also in Division B6] An electromagnetic striker mechansim for a printer comprises (Fig. 2) a U-shaped magnetizable core 11 with polepieces 12, 13 bearing energizing coil 14; an armature 15 being attached to a strike hammer 8 so as to move translationally parallel to the faces of polepieces 12, 13 and to the portions L of the magnetic field of the core traversing the armature; the shape and position of the rest of the armature being such that the reluctance of the magnetic circuit 11, 15 produces maximum force on the armature at the instant of energization of coil 14, (Fig. 6, not shown). Initially the armature 15 is asymmetrical with regard to core 11, and is symmetrically disposed in the striking position; from which it is restored by a spring (not shown) on de-energization. Alternatively, the armature may be of shallow inverted U-shape with arms directed towards core 11 (Fig. 3, not shown) again with maximum force at the instant of energization (Fig. 7, not shown). In further modifications one or both ends of the armatures and the opposed pole faces may be castellated to present a multiplicity of poles, so that for a given striking force the necessary movement may be varied (Figs. 2A, 3A, not shown). In an alternative form (Fig. 8) the striker mechansim comprises a U- shaped core 21 and energization coil 22; the polepieces having part cylindrical surfaces centred on pivot 25 of arcuate armature 27 and supporting member 26; restored by tension spring 37. The armature presents salient poles 28, 29 whose curvature is cylindrical centred on pivot 25, and carries a striker hammer 30 operating against print support 32. A stop 33 defines an adjustable rest position in which the armature is laterally displaced of the polepieces; so that actuating current rotates the armature about pivot 25 to reduce reluctance to a minimum. Adjustment of dimensions X, Y determines the desired time of maximum impact. In a modification (Fig. 9, not shown) the hammer of the device drives a further strike hammer of required mass over a sliding rod having a return spring. The armature may be mounted on an aluminium pivoted supporting member (Fig. 10, not shown). In a further modification (Pigs. 11, 12) a coil 61 is wound on a reduced portion 60 of a magnetic core on either side of which magnetic sidepieces 62, 63 are arranged to pivot on a common shaft 64. The sidepieces are secured to a non-magnetic arm 65 carrying strike hammer 66 with rest position defined by adjustable stop 67; in which the sidepieces are not symmetrical with regard to coil 61. On energization the field traverses the sidepieces parallel to their planes and they rotate about shaft 64 substantially parallelly to the lines of force of the field, and on de-energization are restored by resilient strip 68.

Title: Electrical Apparatus for Converting Alternating/Direct Current
Inventor: PHADKE ARUN GAJANAN
IPC: H02M7/757
Filed: 1967-10-06
Abstract: 1,191,938. Converting. ALLIS-CHALMERS MFG. CO. 6 Oct., 1967 [17 Oct., 1966], No. 45805/67. Heading H2F. In a system for conversion between A.C. and D.C. in either direction using a plurality of rectifiers (e.g. thyristors or mercury-arc valves) which are fired in a predetermined sequence, a plurality of control signals are derived from the A.C. side and one of these is selected and used to produce firing signals for the individual rectifiers. Fig. 1 shows such an arrangement for use in an H.V.D.C. transmission system, conversion being made between 3-phase A.C. on lines 14, 16, 18 via transformer 24 and rectifiers V1-V6 and D.C. on lines 20, 22. Signals are obtained from the A.C. side via a transformer 42 which has six secondary windings for each phase. When power is being transmitted from the D.C. side to the A.C. side, the threephase sine waves from transformer 42 are fed to phase-advance means 38, Schmitt trigger 50, delay means 52 and a selector unit 64 which passes on only one of the six signals, preferably the one which occurs earliest in time and provides the greatest margin in commutation, to allow for deionization in mercury-arc rectifiers. The D.C. level is monitored on line 67 and compared with a reference level in unit 62, any difference being used to control the delay means 52 so that the extinction angle of the rectifiers will be increased for high values of D.C. The selected signal is passed to a pulse-generator 66 which produces six firing pulses for the rectifiers V1-V6 via a bi-stable unit 69. When the circuit is being used as a rectifier, the sine waves from transformer 42 are converted at 58, 60 into a voltage proportional to the sine-wave peak and are integrated in a parallel unit 56. The two are added in unit 61 and compared with a corrective reference signal obtained from the D.C. side via line 67. The resultant is passed via Schmitt trigger 63 to a selector unit 68 which passes on one of the signals to the generator 66 for firing the rectifiers. The generator 66 (a monostable circuit) always receives signals from both units 64 and 68, but responds only to the signal occurring earlier. When the circuit is being used as an inverter, the signal from unit 68 will be the earlier one. The arrangement is stated to reduce harmonics in the A.C. side with less perfect filtering. The circuit can also be used with single-phase A.C., and for higher D.C. voltages a plurality of rectifiers can be used in series.
